Shipping Costs and Your True Profit

Shipping quietly reshapes your margins. Here is how to account for it honestly.

Shipping is a real cost

Whether the customer pays for shipping or you absorb it, the cost is real and it affects your margin. Treating shipping as separate from profit is how makers end up making less than they think.

Know your actual cost per order

Shipping cost varies by size, weight, and destination. Knowing the real cost for the orders you actually send, rather than a rough guess, is what makes your margin calculation honest.

Decide who pays, deliberately

Free shipping can boost sales but eats margin; charged shipping protects margin but can deter buyers. Whichever you choose, make it a deliberate decision with the real cost in view, not an accident.

Fold it into the margin

The clearest picture comes from including real shipping cost in your per order margin. Then the profit you see is the profit you keep, after the box has actually reached the customer.

Key takeaways

Shipping is a real cost, paid by you or the customer
Know your actual shipping cost per order
Decide deliberately who absorbs shipping
Include shipping in your true per order margin
